TO ALL WHOM IT MAY CONCERN:

Be it known that-I, STEPHEN CHAMBERLIN, of Boston, have invented an, Improved Tip-Sled; and I do hereby dec drawings which accompany and form part of this specifi enable those skilled in the art to practiseit.

The object of my invention is to construct sleds for cartage of coal,sand, may he slid or tipped out from them,the same as with common dump or tip-ca in so mounting asled-body upon its runners that its rear end ma charge the load by gravity.

The drawings represent a sled embodying my invention.

A shows a sideelevation; B, an end elevation thereof. a a denote the runners; b, the sled body, mounted on an axle, c, which is supported in high bearings, d, as seen at A. The axle turns or tips in these hearings, a cap, e, holding each axle down, and allows the body to be tipped, as seen by the lines in red at A. The front end of the body is supported on an upright,f, and is held down thereto by a ring and book, as seen at g, or by in the county of Suffolk, and State of Massachusetts, lare that the following, taken in connection with the cation, is a description of my invention suflicient to gravel,- &c.; that their contents rts; and my invention consists y be tipped'down to a, suflicient angle to disany other suitable device, the ring being slipped from the hook to tip the sled, as will be readily understood.

away to allow the body, when tipped, to come down to, or almost to, the surface of the ground, as seen at A, the load being thereby dumped without danger of overturning, or o'f tipping up the runners.

The means of connecting the body to the runners or runner-frame or truck, and arrangement, may be varied from that described, although the construction sh and most practical. Double runners may be used if or when desirable.

The invention supplies agreat want in moving coal, gravel, &c., when snow lies upon the ground, and obviates the necessity of using wheel-carts for tipping, or of shovelling out the material'if sleds are used.

It willbe obvious that the bearings a may be placed, across the sled, instead of lengthwise thereof, so as to have thebody tip at the side instead of at the back, as will be readily understood. I claim, in combination with the sled-runners, a body so mounted as to tip,

and the general construction own is considered the simplest substantially as described.
